The baffle has a leading edge, a trailing edge located behind the leading edge with respect to the belt travel direction and below the leading edge with respect to a vertical direction, and a baffle surface extending from the leading edge to the trailing edge. One or more sieves are located below the baffle, and a fan is provided to direct an airflow at least partially upwards in the vertical direction adjacent the rear roller. A method for separating grain is also provided.
